RB1 associates with and stabilizes pancreatic duodenal homeobox-1 (PDX1) that is essential for embryonic pancreas development and adult beta-cell function

ATF3 interacted with PDX1, and effectively inhibited EP300-mediated transcriptional coactivation of the PBE-containing promoter, whereas C-terminal domain-deleted ATF3 did not inhibit the transcoactivation of EP300

PDX1 is important for GPR27 effect on the insulin promoter and insulin secretion

key role of PPARG in regulating pancreatic beta-cell function by improving the stability of PDX1 and MAFA proteins

PDX1 contributes to the transcriptional transactivation of ALX3 in pancreatic beta-cells by acting in co-ordination with USF1 and USF2 (pMID: 25040025)
